I am unable to see sand or anything else I select. I can see rippling from heat and explosions but do not see any objects.

i am using reddit/r/toz to share the latest changes and experiments. format looked ideal since i can both share the experiments on related channels cellular_automata/proceduralgeneration/.. and have a copy on r/toz. they employ all the vile practices that is common to popular aggregators/forums. geolocking/shadowbanning/removing-without-notice/removing-until-post-disappears-to-irrelevance. i believe i am both geolocked and actively targetted (in some dystopian list). this has been going on for some time ...

I am wondering What can we expect from this game in the future ? Will we get some sort of incredible machines type of levels ?

its dead now. Dev please read this and update it.

It's been a long time since an update. I think you should create a discord server too keep the activity up.
